Magic manipulation: it's the way that allows the users to manipulate objects or things. Also, it is one of the basic abilities that should everyone know since this is mostly used in the Academy in this strange world.
Riku heard this kind of stuff in the novel and manga he read so he had an idea what it was. But the problem here was, he didn't know how it exactly work. Remember, the power in the world he came from was called "Gene's mutation." Where was the monster's gene transfer to a certain human body. By doing this, they would grant the power and physical strength that the specific gene that has.
"It seems that you're not familiar with the magic that this world had. Can you tell me where you exactly came from?" Naina asked him with a serious tone.
She was narrowly looking at him within the eight meters gap they have, at the same time, she was blinking her eyes for some reason.
If Riku answered her straight to the point, there was a chance that this woman wouldn't believe him. Or to be exact, who was the stupid person who believed that there was another world besides the world that they had. Aside from that, he can't tell his reason for the being, why? He was just simply avoiding any small suspicion that would surely give him a hard time perfectly doing his main job here.
"Sorry to say, but I can't still remember the place where I really came from after the Arzotoc's guard tortured me. The only thing I can remember besides my name is the object, or easy to say, the information to create a new invention." Riku said these words without stuttering in order to make them more realistic.
In his opinion, filling all the holes in his made-up story could help him to avoid all the possible questions that would throw at him. Aside from that, adding that he had been tortured by the guards helped him to strengthen the story that she had.
At this point, Naina could easily tell that this man didn't belong in the Arzotoc Village because of the rumors she heard from the other villagers.
"Ohh... So you're that person." And all of a sudden, she bowed her head to apologize. "Sorry about that, Riku Hirota, we admitted the guards in this village did the big mistake of torturing someone like you."
Well, it went to Riku's mind that all the people in this village hadn't had the same behavior as there were people who have well manners just like Henry and Naina.
"You don't need to apologize, also, you can call me Riku since I would surely spend my whole time staying in this library." Riku had a broad smile on his face, so Naina would have a good impression of him.
"Is that okay with you that I just called with your first name? You're an inventor and I'm the librarian so I think your current position is superior to mine. I just saying this because I don't want to disrespect you." Naina explained her side formally, at the same time, blinking her eyes several times. Or to be more simple, she noticed that this man was hiding his face by using white clothes.
He raised his shoulders a bit, knowing calling him Riku wouldn't a big problem. "That's fine, Naina, I don't see any problem by calling me that..." He paused for a second since the Naina's eyes movement piqued his attention.
What she was doing?
At first, he thought Naina was curious to see his face. Around him was the radiance glittering light given by the magical books and huge chandelier above him. In this situation, it was safe for him to remove the clothes on his face.
Even though he removed it. Naina's action was still the same so at this point, his eagerness to know the reason behind this pushed him to question.
"Naina, before we start can I ask you one question?" He said out of his curiosity.
The of them were walking around the library as Naina helped him to familiarize himself in this kind of place. Yet, she nodded her head without making any second thought.
"Sure, Riku, as long as I could answer your question it doesn't matter to me." She responded politely and can't stop frowning her brows.
"Hmm... It's just simple questions, but can you tell me why are you continuously closing your eyes? There's a wrong with my face?" Riku asked her in a deep tone.
She uncontrollably shook her head come along with a bothered expression. "No, no, no, Riku! I just have a problem with my eyes so I can't stop my eyes from blinking." She responded and planned to bow again her head at him to sincerely apologize, but Riku stopped her.
"You don't need to bow at me, we are just the same people here." He said seriously before adding these words. "Problem? Do you have a problem with your eyes? It's like blurry or something?"
"Yes, Riku, how did you know about that?" Naina asked him curiously, then walked closer to him so that she can clearly see his face.
Of course, having blurry eyes was just an ordinary occurrence for all the people inhabiting each section of this world.
"Hmm... I just know people that have the same case as you." He did the same thing, he went towards her, then checked her eyes. His fingers were touching his face just to make sure that there was a sign this woman would be blind.
"E-Eh? W-Wait, R-Riku, what are you doing?" Naina stuttered as she became uncomfortable when Riku was gently touching her face.
He deeply sighed as he clarified that this woman's eyes can become better. But the thing here, he had no idea how long this woman experienced this and how blurry her eyes were.
"Hais... You're just lucky that you have blurry eyes. You should fix it before it can become worst." He advised him politely, then planning to proceed in his job.
"Yes, Riku, once I succeed to find the suitable healing magic with this condition." Naina cheerfully said.
"What do you mean by that? The healing magic can't cure your blurry eyes?" He asked him once again.
She nodded her head, "Yes, the healing magic just focuses on taking back all the affected parts of your body into their original states. In my case, I'm born with blurry eyes so healing them is just useless."
Riku easily understood what she was trying to say to him. Can't heal everything just like the blurry eyes of Naina. Moreover, he already knew how he was going to resolve her problem.
To become her friend. It was his main problem so that he can explore different kinds of books in this library since from the being he was just allowed to know the information where he can find the materials he needed to build the pipeline.
"If that's the case, I will try to help you to have good eyesight." He confidently said and smiled at her.
"Really?! Are you sure you can do that? Also, what kind of incantation magic would you use to cure my eyes?" By hearing these words, Naina would look so excited as her eyes would always give him a hard time.
Riku had a malicious smile on his face. 'Hmm magic? Are you kidding me? It's just simply information that I have in the world where I came from.' He uttered to his mind, at the same time, planning to surprise this woman that was certain that she had never been heard before.
"I can't tell the full details right now but everyone called the Magic of Science."
Naina was blinking her eyes, but this time it wasn't because of his blurry eyes since she could clearly see the handsome face of the man standing in front of him. It was because she had no idea the words spitting out of this man's mouth.
"Magic of Science? By hearing this name I can easily tell that it's a strong branch of magic." Naina said slowly.
"Of course, but it had a lot of processes. So I need your help before we can do that, also, I know you want to learn to it, right?" Riku said, then officially started his research.
"Yes, Riku! I'm happy to help an inventor like you!"

His research was starting. Naina was given all the books that had information on all the materials that Riku was looking for. He was reading where he could find the iron, copper, silver which was a good conductor of electricity, etc. Come along with his research, he was also looking for the glass or materials to build a contact or glasses for Naina's blurry eyes.

The night came up. Riku already come back to his room and immediately laid on his made because of exhaustion. Spending twelve hours reading different books made him dizzy since some of the characters were new to him. Moreover, he was glad as he already knew where he should start first.
"By starting tomorrow, I will find the materials in the Assima forest!"
